Privacy Policy

1. Overview

BillWise ("we", "us", "our") is committed to protecting your privacy. This policy explains how we collect, use, store, and protect your personal information when you use the BillWise platform at billwise.com.au, including our energy calculators, bill analysis tools, installer marketplace, and recommendation engine.

Information collected automatically

4. Data Sharing

We share your information only in these circumstances:

We do not sell your personal information to third parties.

5. Bill Upload Security

When you upload an electricity bill for analysis:

• NMI (National Metering Identifier) and account numbers are automatically redacted before storage

• Uploaded bill data is retained for 30 days by default, then automatically deleted
• You can delete your bill data immediately at any time from your account settings

6. Data Retention
